Maybe alternatively you can invert them into doc and give it a number to upload them as img by then I believe they could all enter in single page instead of reserving a space.
Do you think about this @op and does it make sense to you as well?
Posting content as an image is not a good idea. It makes the content hard to access for some users (for example for users who rely on screen readers or inline translators) and is not search-engine-friendly. Text is much better for discussions and sharing information as it can be easily copied, quoted, or shared between platforms and different media.
I see now, that means posting in the first page and reserving the next spacing could be more ideal. Although I never thought of that.
